Anatomy And Function Of The Knee

The knee is a complex joint made up of bones, muscles, tendons, ligaments,
and cartilage. It may be described as a hinge joint, similar to the hinge on
a door. The knee not only bends back and forth but also has a complex
rotational component that occurs with flexion and extension.

Each knee has two crescent-shaped menisci, or cushion pads. The lateral
meniscus lies at the outer side of the knee and the medial meniscus lies
at the inner side of the knee. The strong but flexible menisci act as shock
absorbers between the femur (upper-thigh bone) and the tibia (shin bone),
especially during weight-bearing activities such as walking or stair climbing.
The menisci also stabilize and evenly distribute your body weight across the
knee joint.

The ACL is one of a pair of crucial ligaments that forms a cross in the center
of the knee joint. Both the ACL and the PCL function to stabilize the knee
from front to back. The ACL limits the forward movement of the tibia, and
the PCL limits the backward movement of this bone. Additional ligaments
provide stability to other movements at the joint, including angulation (left/
right motion) and rotation. Without such stability, you may feel that your
knee is simply giving out from under you.

Being pain free where I had spent the last 37 years in a significant amount of pain — this is the biggest gift to me.
The beauty of this particular technology is that it removes what it needs to and nothing else. It's accurate.

The NAVIO system is not for everyone. Children, pregnant women, patients who have mental or neuromuscular disorders that do not allow control of the knee joint
and morbidly obese patients should not undergo a NAVIO procedure. Knee replacement surgery is intended to relieve knee pain and improve knee functions.
However, implants may not produce the same feel or function as your original knee. There are potential risks with knee replacement surgery such as loosening,
fracture, dislocation, wear and infection that may result in the need for additional surgery. Longevity of implants depends on many factors, such as types of
activities and weight. This information is provided for informational and educational purposes only, and is not intended to be nor should it be construed as medical
advice. Consult your physician for details to determine if a NAVIO robotics assisted procedure is right for you. The NAVIO system is intended to assist the surgeon in
providing software-defined spatial boundaries for orientation and reference information to anatomical structures during orthopedic procedures. The NAVIO system
is indicated for use in surgical knee procedures, in which the use of stereotactic surgery may be appropriate, and where reference to rigid anatomical bony
structures can be determined. These procedures include unicondylar knee replacement (UKR), patellofemoral arthroplasty (PFA), and total knee arthroplasty (TKA).
The NAVIO system is indicated for use with cemented implants only.
